Here are 2 options for Megillahs with a simplified version of the story. Not what you're looking for? You can email me using the contact form, and I may be able to help you out.
The first Megillah is entirely photo scenes, and the second megillah is about 60% gluing activities, and 40% pictures. Both options are available to download here.
You will need the following costume items for the pictures:
Girl's Dress Up- a lot! :)
Haman's hat- or a Pirate hat
2 soldier hats
Kippahs and hats
Tea Set/Play food
Any other fun royal accessories

Happy Purim and Happy Posing!
